How does Gregor's mother react to seeing Gregor for the first time after his transformation in Kafka's The Metamorphosis?

The narrator describes
Mrs. Samsa's response to seeing her son, after his metamorphosis:

His motherin spite of the manager's presence she stood with her hair still unbraided
from the night, sticking out in all directions -- first looked at his father with her hands
clasped, then took two steps toward Gregor, and sank down in the midst of her skirts spreading
out around her, her face completely hidden on her breast.

Her first reaction, then, seems to be one of utter disbelief. Mrs. Samsa appears to
look to her husband for confirmation of what she is seeing. Then she seems to feel an impulse to
go to her son, to comfort or assist him in some way, but before she reaches him, she sinks to
the ground, indicating that she has lost hope. Her head is down, and this particular posture
tends to imply dejection and sorrow.

A little while later, during this same
interaction,

she, who had seemed so completely
self-absorbed, all at once jumped up, her arms stretched wide, her fingers spread, and cried,
"Help, for God's sake, help!" held her head bent as if to see Gregor better, but
inconsistently darted madly backward instead; had forgotten that the table laden with the
breakfast dishes stood behind her; sat down on it hastily, as if her thoughts were elsewhere,
when she reached it; and did not seem to notice at all that near her the big coffeepot had been
knocked over and coffee was pouring in a steady stream onto the rug.

It is obvious that Mrs. Samsa feels either herself, her son, her
family, or all of them, to be in need of help, perhaps to know how to deal with her son in his
terrible new condition, but it is not totally clear who she expects to help them. The manager?
That seems unlikely. It appears that she is still attempting to understand what Gregor's new
state actually is, but, at the same time, she is so horrified and frightened by what she sees
that she cannot help but run away from it. She has forgotten her breakfast and doesn't seem to
notice anything else that is going on around her. It seems a lot like disbelief and
horror.
